expose git hooks through an event emitter
npm install git-emit-node7git-emit
========
Expose git hooks through an EventEmitter.
This module is super handy when used in conjunction with
pushover.
example
=======
reject.js
---------
`` js
// randomly reject 50% of commits
var em = require('git-emit')(__dirname + '/repo.git');
em.on('update', function (update) {
if (Math.random() > 0.5) update.reject()
else update.accept()
});
`
Now we can create a new bare repo and run reject.js to listen for commits:
``
$ git init --bare repo.git
Initialized empty Git repository in /home/substack/projects/node-git-emit/example/repo.git/
$ node reject.js
The first time, our commit is rejected:
``
$ git push ~/projects/node-git-emit/example/repo.git master
Counting objects: 43, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (36/36), done.
Writing objects: 100% (43/43), 6.15 KiB, done.
Total 43 (delta 18), reused 0 (delta 0)
Unpacking objects: 100% (43/43), done.
remote: error: hook declined to update refs/heads/master
To example/repo.git
! [remote rejected] master -> master (hook declined)
error: failed to push some refs to 'example/repo.git'
but the second time, the commit goes through!
``
$ git push ~/projects/node-git-emit/example/repo.git master
Counting objects: 43, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (36/36), done.
Writing objects: 100% (43/43), 6.15 KiB, done.
Total 43 (delta 18), reused 0 (delta 0)
Unpacking objects: 100% (43/43), done.
To example/repo.git
* [new branch] master -> master
It works as expected hooray!
methods
=======
var gitEmit = require('git-emit')
var emitter = gitEmit(repoDir, cb)
----------------------------------
Install hooks into repoDir. repoDir should be either a .git directory fromgit init --bare
an existing or new project or just a bare git directory created with.
repoDir should not have any existing hooks unless they were created with
git-emit.
Optionally pass in cb(err, emitter) to be notified when the hooks have beenrepoDir
installed into or an error has occured.
emitter.close()
---------------
Shut down the dnode listener used internally by git-emit.
events
======
You can listen for events corresponding to github hooks.
All events receive an update object.
Passive events fire and cannot influence the acceptance any actions.
Abortable events MUST respond to the update object with either
an update.accept() or an update.reject().
passive events
--------------
* post-applypatch
* post-commit
* post-checkout
* post-merge
* post-receive
* post-update
* post-rewrite
abortable events
----------------
* applypatch-msg
* pre-applypatch
* pre-commit
* prepare-commit-msg
* commit-msg
* pre-rebase
* pre-receive
* update
* pre-auto-gc
update object
=============
All events are passed an update object as the first argument.
Abortable updates MUST call update.accept() or update.reject().
Since there may be multiple listeners for any update, all listeners must
accept() an update for it to be ultimately accepted.
update.accept()
---------------
Accept an update.
update.reject()
---------------
Reject an update.
update.arguments
----------------
The raw arguments provided to the git hook on the command line.
update.lines
------------
An array of lines from process.stdin.
This attribute is only defined for pre-recieve, post-receieve, andpost-rewrite` hooks.
update.canAbort
---------------
Whether the update is abortable.
install
